Method for refining Molten Steel for controlling phosphorus content in Converter

摘要

The present invention relates to a converter refining process, the slag basicity (CaO / SiO ₂ ) and maintained in the 2.0 to 3.0 provides a converter refining method of the phosphorus (P), characterized in that the control component in the molten steel from 200 to 300ppm. ; converter refining process of the present invention by controlling the slag composition in the slag basicity (CaO / SiO ₂ ) by a reduction , which can increase the of phosphorus (P) of molten steel components advantages there is .
